T440s flickering / blanking symptoms on external monitors connected to Pro Dock

2017-04-20, 18:48 PM

I have 3 T440's at my company that all have flickering dual external monitors

-T440

-dual lenovo lcd monitors (59 Hertz, 1920x1080, landscape extended display)

-display port and vga (we have also tried display port+hdmi to mini display port)

-thinpad pro dock type 40A1 20v

-90w power supply

 

We have tried swapping out monitors (same model lenovo lcd), power cords to monitors, docking staition+ power supply (90W), and swapped out the power strip. http://download.lenovo.com/ibmdl/pub/pc/pccbbs/options/fwdphb01.exe I am unable to install this driver it doesn not seem to run even as local admin it will not work. I have run windows updates, updated intel graphics driver..I'm out of ideas. Any help or solution if you have had this issue is greatly appreaciated!
